# Pivot Confusion

The Pivot System allows you to change the centre point of a BasePart or Model. This information is not always presented intuitively, so here's a simple breakdown.

BaseParts use PivotOffset, Models use WorldPivot

1. A BasePart's PivotOffset is simply a cframe relative to its current origin
2. Models without a PrimaryPart use WorldPivot which is a cframe of the current origin, there's no relativity, it's just an arbitrary spot, usually based on the first child it can find. If there are no children, then it has no meaning
3. Models with a PrimaryPart also use WorldPivot, but it's based on the primaryparts origin + its pivotoffset, as if it was just copying that parts pivoted origin. This can be a little confusing as currently a Model with a primarypart will only display the primarypart's PivotOffset and not the models WorldPivot
